I'd be very happy to do a swap, if you don't mind invalidating your insurance (undeclared modifications and all that stuff). There are mirrors on e-Bay that are ALMOST right, but I hope to get a matching one before too long. I used to be a Beetle owner, and still have an equivalent mirror for the passenger side, which you can have as a matched (almost) pair of cyclist killers, and can take out two cyclists/pedestrians at the same time. My daughter was unhappy about my taking her daughter out in the Beetle, (on safety grounds) although she herself had got married from it - maybe the fact that she and her bridesmaid had to push it to get it restarted after we stopped to put on the ribbons affected her judgment - but doesn't everybody know that the starter solenoids get sticky when the engine has run for more than an hour?
So I now have the safest car of its generation, (which was what I got married from and went on honeymoon in) and don't want to squander its credentials by a beautiful and very clever modification which is potentially lethal. So if anyone has a correct period driver's door mirror that they can spare, (or a matched pair) they will make an old man very happy - but I'd prefer not to have the sixties' round mirrors, or wing mirrors.
Thanks,
